Table & Column Mapping in the Fluent API We have done some work to make the mapping of classes/properties to tables/columns simpler and more intuitive in CTP5. We are still working to improve the quality of this new work, particularly around the mapping of inheritance hierarchies.

Pluggable Conventions CTP5 includes a very early preview of this feature that is not complete and has not been extensively tested.

The new Validation feature is currently only supported when using Code First
